Location of client header files

I need to compile a complete list of different locations to find 
"libpq-fe.h" in various PostgreSQL distributions so that I can 
automatically add the correct path when compiling a client application.  
Please post the location "libpq-fe.h" for your distribution and I will 
compile a list and post it back to pgsql-hackers.

Thanks.
Tim
